My invention relates'to improvements in the method of and machine .for working pieces of dough, and the object of the improvements is to provide a method by '5 means of which pieces of dough can be worked into oblong form to produce therefrom oblong rolls, the dough being previously thoroughly worked by circular or oval working operation for reducing the pores 'produced by fermentation to uniform size.

With this object in view my invention conmentation and baking of the same. By imparting difierent numbers of longitudinal working movements to the pieces of dou h the desired .form can be imparted to the ro s,

the said rolls having, after baking, a slightao 1y oblong circular form, oval form, or elliptical form, and the rolls being provided at the eniis with points. or having round ends.

In carrying out my improved method I make use of a machine in which the compartments of the working apparatus are in the form of oblong hexagons or the like having parallel sides and placed directly adjacent to each other and one beside the other, or disposed suitable distances apart as is'necessary for the following fermentation and baking of the rolls. A working apparatus of this type can be used in working machines of any known of preferred construction, so that by means of any working machine or by means of any dividing or working machine the-pieces of dough can be worked into round or oblon form. It is desired to work 'oblong pieces 0 dough on a machine originally designed to work round pieces of dough, my im- 50 proved working head or dividing head is ing machine,

195,634, and in Germany April as, 1926.-

mounted on the said machine without otherwise reconstructing the same.

Other objects of the invention will appear from the following description. 7

For the purpose of explaining the invention several examples embodying the same have been shown in the accompanying drawings, in which the same letters of reference have been used in all the views to indicate corresponding parts In said drawings, 60.

The general construction of the dough working machine of which my invention is an improvement has been shown and described in the patent of the United States to Bertram, No. 1,303,454, dated May 13, 1919.

Referring now to the example illustrated in Figs. 1 and 2, the working machine comprises a frame a part 1 of which has been shown in Fig. 1. In vertical bearings of the said frame shafts 2 and 3 are rotatably mounted, each of which carries at its bottom end a crank pin 4 and 5, and the said crank pins are made integral with crank pins 6 and 7 respectively disposed eccentrically of the crank pins 4 and 5, the eccentricity of the pins 6 and 7 relatively to the shafts 2 and 3 being larger than that of the pins 4 and 5 relatlvely to the said shafts.

The crank pins 4 and 5 are in engagement with slots 8 and 9 formed in a plate 10, and the crank pins 6 and 7 are in engagement with with slots 11 and 12 of a plate 13 located below the plate 10, and the plates 10 and 13 are connected with each other by means of a hub 13. The slots 8 and 9 are disposed perpendicularly of the slots 11 and 12. The downwardly directed part of the disk 13 is formed with a flange 14 carrying at its bottom side a ring 15 connected by means of screws 16 and 17 with a ring 18 located on the flange 14. The screws 16 and 17 are passed through segmental slots 19 and 20 of the flange 14, and they have a certain play relative thereto. Supported from the ring 15 by means of holders 21, 22 are the dividing .knife blades 23.

The disk 24 is secured by means of screws 25 and 26 to the bottom end of a vertical shaft 27, and it is rockingly mounted on the said shaft in the same way as the ring 15 is mounted on the flange 14. The construction of the ring 28, the lower presser or dough dividing plate 29, and the table 30 are similar to the construction of parts now in use, and I deem it not necessary to describe the said parts in detail.

After unscrewing the screws 16, 17 and 25, 26, the working head consisting of the parts 23, 24 and 28 can be turned at an angle of 90. To the disk 13 and the working apparatus suspended therefrom an oval gyratory movement is imparted by means of the crank pins 4, 6 and 5, 7 cooperating with the slots 8, 9 and 11, 12 in a manner readily understood.

In Fig. 3 I have shown the dough dividing member 28. As appears from the said figure, the dough dividing member consists of a plate divided by dividing blades 23 into oblong hexagonal compartments 31. In the example shown in Fig. 3, the said compartments are located close to one another, while in the modification shown in F i 4 the compartments 31 are disposed suita le distances apart corresponding to the distance between the worked pieces of dough when fermenting and baking the same. The arrangement of the working compartments 31 shown in Fig. 4 is provided in machines in which the pieces of dough are divided by means of a separate dividing apparatus prior to working them in the compartments 31. In some cases the corners of the compartments are rounded, as is indicated in dotted lines at the right hand bottom art of Fig. 4, the said modification being a visable particularly where the plate formed with the compartments is not used for dividing the dough, but only for working the same.

When disposing the working apparatus so that the compartments 31 and 31 are dis posed with their longitudinal axes in the direction of the larger axis of the oval movement, the pieces of dough are worked into round form though the compartments are ,oblong in form. By turning the working apparatus at an angle of 90, and so that the larger axis of the oval movement is disposed transversely of the longitudinal axis .of the compartments, the dough is worked into oblong form. in Figs. 5 and 6 I have illustrated both operations. In the said figures the parts 291 and 292 of the lower working plate 29 which in the operation of the machine are not engaged by the bottom edges of the walls of the compartments 31 and 31 are crosshatched. In Fig. 5 the said portion is'comparatively long, while in Fig. 6 it is nearly in the form of a regular hexagon. Therefore, when operating in the manner shown in Fig. 6, all the side walls have substantially uniform action on the piece of dough which is therefore brought into approximate spherical form.

The diagram shown in Fig. 7 illustrates the path of the plate 13. The shape imparted to the piece of dough 32 within the compartment 31 depends on the character and the number of the operations of the compartment. Figs. 8 to 14 show different forms of the Worked pieces of dough 32. Fig. 8 shows a piece of dough of oblong-rounded form located equal distances awaywfrom the side walls ef the compartment 31. v The piece of dough shown in Fig. 9 has the same general form as that shown in Fig. 8, but it is slightly longer, the number of the operations of the working head tending to elongate the dough being larger than in case of Fig. 8. The said number of operations tending to elongate the piece of dough has been further working operation is nearly completed. In

this case the working operations are performed in the manner illustrated in Fig. 6. Fig. 14 shows the same piece of dough at the end of the working operation.

Various mechanisms may be provided for imparting oval or elliptical movement. For this purpose the mechanism shown in Figs. 1 and 2 may be used, or either one of the mechanisms described hereafter. In the modification shown in Fi s. 15 and 16 the working operations for protfiicing spherical or oblong pieces of dough are performed without first dismounting the wor 'ng apparatus. In the top part of the machine frame 33 a vertical shaft 34 carrying a bevel gear wheel 35, a crank disk 36 and a crank pm 37 is rotatably mounted. The shaft 34 is driven from a bevel gear wheel 38 meshing with the bevel gear wheel 35'and keyed to a main driving shaft 40 carrying a belt pulley 39. The crank pin 37 engages one end of an arm 41 formed with a longitudinal slot 43 engaged by a pin 42 fixed to the machine frame 33. Thus, when rotating the shaft 34 substantially circular movement is imparted to the left hand end of the arm 41, while its right hand end has substantially a rectilinear reciproeating movement.

The right hand end of the arm 41 is formed with a slot 44 engaged by a in 45 screwing in a guide plate 46. At its ottom side the arm 41 is formed witha lon 'tudinal slot 47 engaged by a pin 48 carried a slide 49 and .a dapted to be shifted relative to the slot 47 by means of a-link 51 connecte to a bell crank lever 52 the outer arm of the said bell crank lever carrying aroller or ball 53 straddled by the top end 54 of a controllin rod 55..

By means of the rod 55, the 11 crank lever 52, and the link 51 the slide 49 and the pin 48 carried thereby can be shifted withinthe slot 47 into position with the axis of the pin 48 in ali cut with the axis of the shaft 34. If the pm 48 is thus in axial alignment with .the shaft 34 the movement of the said shaft 34 is transmitted to the guide plate 46 in one direction by means of the pin 45 and the slot 44, and in the direction perpendicular thereto through the pin 48, the slot 47, the slide 49 and the guide way 50. Thus, the dividing or working head 56, which is suspended in the usual way from the guide plate 46,'performs circular working movements. If, however, the pin 48 is shifted by means of the rod 55 to the right and into axial alignment with the pivot bolt 42, the movement of the crank pin 37 is transmitted to the disk 46 in one direction by means of the pin 45 and the slot 44.,

But in the other direction no movement is transmitted to the disk 46, because the pin 42, which is rigidl fixed to the machine frame 33, is in axia alignment with the pin 48. Therefore the disk 47 and the working head 56 carried thereby have only reciprocating movement, so that they work the pieces of dough into oblong form.

In the modification illustrated in Fig. 17 the circular workin operation is performed by a part of the wor ng apparatus, and more particularly by'the top part thereof, while the other part is stationary. For working the pieces of dough into oblong form the bottom part of the apparatus is made operative, while the top part is arrested. The top part of the machine by means of which circular working operation is performed is sim ilar in construction to machines heretofore constructed, an example being described in the U. S. patent to Bertram above referred to.

The pressing or dough supporting plate .is not fixed to the table 57, but it is supported on a plate 59 having reciprocating movement on the table 57, balls 58 being interposed between the table 57 and the plate 59 to reduce friction. The said balls engage in suitable re cesses provided respectively in the top and bottom faces of the parts 57 and 59 as is known in the art. The balls 58 are guided in the said recesses so that the plate 59 can be reciprocated in one direction onl and, as shown, from the right to the left in Fig. 17. To the plate 59 a bolt 60 is fixed whichdepends downwardly therefrom, and which is tion clutch the member 68 of which is fixed to a bevel gear wheel 69 meshing with a bevel gear wheel 691 carried by a shaft 692 operatively connected with the upper working mechanism? The sleeve 66 is adapted to be shifted longitudinally of the shaft 65 by means of a link 70 engaging a lever 71 em-' bracing the said sleeve and rockingly mounted on the machine frame 72 at 711. When shifting the link 70 upwardly the 68 intov coupling engagement, so that rotary' movement is transmitted from the shaft 65 and the bevel gearing 69, 691 to the shaft 692 and to the upper working mechanism for imarting circular working operation to the ead 56, as is known in the art. If, thereafter, the link 70 is pulled downwardly, the coupling members 6-3 and 64 are thrown into coupling engagement, so that working movement is transmitted from the shaft 65 and through the intermediary of the cam 62 and the connecting rod 61 to the plate 59, so that recipro-.

eating movement is imparted to the said plate. Thus, the previously worked'pieces of dough are worked into oblong form.

In the modification shown in Figs. 18 and 19 the apparatus is constructed for successively working the pieces of dough into spherical and into oblong form; In the top part of the machine frame 73 a beveled ring gear 74 is rotatably mounted the hub of which is formed with an eccentric bore, and which is in driving engagement with a bevel gear 76 keyed to the main driving shaft 75. In the said bore a sleeve 77 is rotatably mounted which is made integral at its bottom part with two arms 7 Sand 79 projecting therefrom in diametrically opposite directions. Below the arms 78 and 7 9 there is a late 80 rockingly connected with the arm 7 8 by means of a bolt 81 screwed in the plate 80. A latch bolt 84 is movabl' mounted in a bore of the disk 80 positione opposite to the bolt 81 and has a projection 83 adapted to seat in a notch 82 rovided in the arm 79. A spring 88 yieldingly retains the latch bolt in its operative po sition. At its top the bolt 84 is made integral with a plate 85, and the said plate is in engagement through the intermediary of a ball or roller 87 with a lever 86 pivoted to the frame 73.

In the position of the parts shown in Fig. 18 the projection 83 engages in the notch 82, so that the plate 80 is connected with the sleeve 77- at two' diametrically opposite points. Therefore, when the gear wheel 74 is rotated a gyratorymovement is imparted to the plate 80 by means of the eccentric sleeve 77, so that the pieces of dough are worked into spherical form. After the pieces of dough have been sufiieiently worked, the lever 86 their larger axis parallel to a line joining bolts 81 and 84.

In Fig. 20 I have shown a modification in which gyratory movement is imparted to the working head 56 by means of a single eccentric driving mechanism the parts of which are located within the casing 90. Mechanism of this type has been shown for example in the aforesaid patent to Bertram. v The machine frame 91 is made integral with an axial sleeve 92 providing a bearing for a tubular shaft 93 capable of being moved therein upwardly and downwardly. At its top the said shaft carries a plate 94, and in slots of the said plate bolts 95 are provided on which rollers 96 are rotatably mounted. On the said rollers 96 a table 97 is mounted, which is capable of rectilinear reciprocating movement, and which is guided relatively to the plate 94 bymeans of bolts 98 projecting from the plate 94 to diametrically opposite directions and passed through eyes 981 depending from the table 97, springs 99 being provided between the plate 94 and the eyes 981 for normally holding the table 97 in median position. At its top the table 97 is formed with small ribs 971 adapted to receive a plate carrying the pieces of dough. lVithin the tubular shaft 93 a rod 102 is guided, which is acted upon by a spring .103 tending to force the same upwardly and into locking engagement with arecess 101 made in the bottom part of theitable 97. The said rod 102 is adapted to be ulled downwardly for releasing the table 9 by means of a bell crank lever 106 acted upon by a belt 105 screwing in the frame 91 and adapted to be slcillewed inwardly by means of a hand wheel The operation of the machine shown in Fig. 20 is as follows: After placing a plate carrying a batch of dough on the table 97, the said batch is first pressed, divided and worked by means of the dividing and working head 56, the said head having gyratory movement so as to impart spherical form to the pieces of dough. After the dough has been sufiiciently worked the rod 102 is pulled downwardly by means of the screw 105, whereupon the table 97 is capable of reciprocating movement on the'rollers 96,- 96. Now the table 97 is carried along by the head 56 moving from the right to the'left or vice versa in Fig. 20, the

and the bolt 84 are forced downwardly by resistance of the pieces of dough located between the head and the table 97 exceedin the resistance opposed to the movement 0 the table 97 and the springs 99. Thus the working head 56 is reciprocated relatively to the table 97 in a direction perpendicular to the direction of the movement of the table 97 on the rollers 96, and the pieces of dough are worked into oblong form.

The operation of the device shown inFig. 20 will be better understood from an inspection ofthe diagrammatical views shown in Figs. 21 and 22. Fig. 21 is a top plan view of the working head 56, and the eccentric has been shown in dotted lines. The circular working movement of the head 56 is composed of two movements of the head performed in two perpendicular directions, the said directions of the reciprocating movements being indicated bythe arrows A, B and C, D. Fig. 22 is a diagrammatical plan view of the table 97 which table is capable of reciprocating in the direction of the arrows C and D. If now the locking rod 102 has been retracted from the table 97, the said table 1s adapted to reciprocate in the'direction of the arrows C, D. Thus, the movement of the working head in the direction of the arrows C and D is compensated by the movement of the table 97 in the said direction, so that only the component of the movement in the direction of the arrows A and B is effective, by which working movement in one direction is imparted to the pieces of dough.

- I wish it to be understood that my invention is not limited to the mechanism shown herein for retracting the .rod 102 from the table 97 and that in some cases automatic means may be provided for this purpose. Further, the movement of the table 97 in one direction by the working head 56 may be supported by springs or the like.

In machines of the type referred to the dr1v1ng eccentric should be constructed so as to be adjustable, in orderthat small and large pieces of dough can be worked by means of the same parts. Now, in order to prevent relative angular displacement of the presser plates by eccentric pressure, which angular displacement; would cause the dough to be pressed to one side of the presser plates, the eccentric drive is constructed so that when arresting the machine at the end of the workmg operation the crank in assumes a positlon central to the machine. For this purpose the crank pin is mounted on a fly wheel or disk tending to return the same into central position. Thus working operation is transmitted through the said fly wheel or disk and its crank pin after startin the machine, and the eccentricity of the era pin is varied by means of the fly wheel or disk. The member performing the working operation is automatically set relatively to the stationary member in central position before the pressing operation begins.

In Figs. 23 and 24 I have shown an example in which the driving shaft 107 carries a disk 108 formed with an eccentric circular hole having a circular disk 109 mounted therein. The disk 109 is adapted to be turned within the disk 108 at a certain angle, and in the example shown in the figures at an angle of 180. The disk 109 carries a crank pin, 110 which, in the position shown in Figs. 23" and 24, is in alignment with the shaft 107,.

and whichv after turning the disk 109 at an angle of 180 has its largest eccentricity relatively to the shaft 107. The disk 109 is formed circumferentially with a segmental groove 111 the circumferential length of which is a little more than one half the than 180, and the screw can be fixed in the desired position by means of a hand wheel 116 screwing thereon.

When the shoulder X of the disk 109 is in engagement with the shoulder Y of the lug 112 the crank pin 110 is in axial alignment with the shaft 107, so that it does not perform gyrator movement when rotating the shaft I however, the disk 108 has been rotated relatively to the disk 109 into position with the head 113 engaging the shoulder Z of the disk 109, the screw 114 being fixed in the position shown in-the figures by means of the hand wheel 116, the crank pin 110 is eccentric relatively to the shaft 107, so that it is capable of imparting gyratory movement to the working head. With the screw 114 1n the position shown in Fig. 24 the largest working strokes are imparted to the working head. When shifting the screw 114 and its head 113 in circumferential direction towards the shoulder Z of the disk 109 the eccentric ty of the crank pin 110 and therefore the s1ze of the working strokes are reduced. Thus the apparatus can be set in any positlon between the said maximum and mimmum for imparting the desired working strokes to the the working head per orms a gyratory movement, the diameter of the circle depending on the position of the screw 114 within the slot 115 of the disk 108. When arresting the machine the operation-is reversed, the (115k 108 is first arrested while the disk 109 continues its movement by reason'of the inertia of the working head, until the shoulders X and Y are a ain in engagement with each other. There y-the workmg head is again brought into central position.

In the modification shown in Figs. 25 and 26 the crank pin of the driving apparatus is returned into central position by means of members subjected to centrifugal force. The disk 117 keyed to the shaft 107 is formed with a diametricalguide way 118 having a slide 119 shiftable therein, the said slide car rying the crank pin 120 and two bolts 121 and 122. On pivot bolts 123 and 124 fixed to the disk 117 two bell crank levers 125 and 126 are rockinglymounted, the short arms of the said bell crank levers engaging the bolts 121 and 122 carried by the slide 119, and the long arms carrying weighted bodies 127 and 128 and being connected by a spring 129 tending to rock the same inwardly.

When rotating the shaft 107 the weighted bodies 127 and 128 are thrown outwardly by centrifugal action, thus shifting the crank pin 120 out of axial alignment with the shaft 107 and with the end face 70 into engagement with a screw 130 screwing in the disk 117, the said movement being transmitted from the weighted bodies to the slide 109 by means of into the piece of doug the bell crank levers 125 and 126 engaging the bolts 121 and 122. The screw 130 is adapted to be set into the desired position for varying the eccentricity of the crank pin 120 by means of the hand wheel 131.

Otherwise the operation of the apparatusis the same as that of the apparatus described with reference to Figs. 23 and 24:.

In Fi 27 I have shown a top plan view of one o the working portions of the surface of the working table 13a, the walls of the working compartment being shown in section. The said working portion is formed with a longitudinal recess or slot 132 and stepped ridges 133 surrounding the said recess or slot. The configuration of the working surface is particularly designed for working the dough into oblong form, but when properly moving the working head the pieces of dough may also be worked into spherical form. If desired the slot or recess 132 may be bridged at one or more points.

Figs. 28 and 29 show the working compartment in different positions relativel to the working portion of the working ta 1e. shown in Fig. 28 the working compartment is in its outermost position relatively to the working portion 132, 133. As appears from the said figure, the recess and the ridges of the working portion tend to hold the pieces of dough when imparting working movement thereto transversely of the recess 132, so that the skin of the piece of dough is put under tension.

Fig. 29 shows the compartment in the position after performing about of the movement of the driving eccentric. The fi ure shows how the skin is contracted at the ottom part of the piece of dough, and that the dough is overthrown in the manner of waves, whereupon it is again compressed at its bottom part when the right hand wall of the compartment which in the position shown 1n the. figure makes contact with the dough 18 further moved to the left. These operations are repeated during each working) stroke transversely of the recess 132, so that y each working stroke a part of the skin is folded h at the bottom part thereof, and the skin is put more and more under tension at the longitudinal sides of the piece. The said action is always performed partments,

on the long sides of the piece of dough being elongated, whereby the worked piece of dough loses more and more its tendency to assume its spherical form.

The recess 132 may be in the form of an elongated depression of the table 134, as is shown in Figs. 28 and 29, or it may be in the form of a slot passed all through the thickness of the table.

The gyratory movements for forming the pieces of dough into spherical and oblong form may also be performed by the table, or the may be performed in art by the table an in part by the working cad.

While in describing the invention reference has been made to particular examples embodying the same I wish it to be understood that my invention is not limited to the constructions shown in the drawings, and that various changes may be made in the general arrangement of the apparatus and the construction of its parts without departing from the invention.
